Industrial sealing component
The Zoro Select Buna-N O-ring kit supplies fifty identical rings with a 15 mm inside diameter and 1 mm cross-section for maintenance technicians who need reliable static or dynamic seals in metric-dimensioned equipment. Each ring is manufactured to a 70A durometer hardness and coloured black for quick visual identification in parts bins.
Fits standard 15 mm grooves
The round cross-section seats directly into a 15 mm nominal groove without shims or adapters, while the 17 mm outside diameter fills the gland completely. Buna-N material resists common hydraulic fluids, lubricating oils and water-glycol mixtures, so the same part number covers multiple fluid circuits across a workshop.
Consistent compression over temperature
Rated from -40 to 250 degrees F, the medium-hard compound maintains sealing force during cold starts and sustained heat cycles without permanent set. FDA-approved formulation also permits incidental food-contact use, and the metal-detectable additive supports contamination-control programmes that rely on inline detection rather than X-ray inspection.

Questions about this item
What is the highest continuous temperature the Buna-N material can withstand before it starts to degrade?
The O-ring material is rated for a temperature range up to 250 degrees Fahrenheit.
How much heat does the seal generate when compressed in a gland during extended operation?
As a static elastomer seal, the O-ring itself generates no heat; any temperature rise comes from the surrounding system fluid or environment.
What gland dimensions or groove standards are required to install these 15 mm inside diameter rings correctly?
The rings have a 1 mm cross-section and 15 mm inside diameter, requiring a metric gland sized for those actual dimensions.
